Abstract

For reading of contactless integrated circuits there is designed an equipment comprising a loop antenna (5) for transmission of oscillating magnetic field and means for detecting a contactless integrated circuit having an antenna coil and further provided with means for emitting short magnetic field pulses, means for detection a signal of an envelope of pulses detected from the loop antenna (5) which correspond to the magnetic field pulses and means for monitoring changes of the amplitude of the envelope of detected pulses and further provided with two independent sources (6,8) of high-frequency magnetic field, the first one of which being a source (6) of nominal output power pulses for communication with a contactless integrated circuit (7) and the second one of which being a source (8) of power output pulses of at least one order of magnitude lower than the nominal output power pulses, for mode of detection of presence of a contactless integrated circuit, while each of the two sources (6,8) of high-frequency magnetic field have a control circuit coupled to a common control unit.
